Preface
Studio 5000 Environment
The Studio 5000™ Engineering and Design Environment combines engineering
and design elements into a common environment. The first element in the
Studio 5000 environment is the Logix Designer application. The Logix Designer
application is the rebranding of RSLogix™ 5000 software and will continue to be
the product to program Logix5000™ controllers for discrete, process, batch,
motion, safety, and drive-based solutions.
The Studio 5000 environment is the foundation for the future of
Rockwell Automation® engineering design tools and capabilities. It is the one
place for design engineers to develop all the elements of their control system.
ControlLogix Controllers
Overview
There are three types of ControlLogix® controllers available. These types include
the following:
• Standard ControlLogix controllers
• Extreme environment ControlLogix controller
• Safety GuardLogix® controllers
This manual explains how to use standard and extreme environment
ControlLogix controllers.
For more information about using safety GuardLogix controllers, see the
GuardLogix Controller Systems Safety Reference Manual, publication
1756-RM093, or the GuardLogix Controllers User Manual, publication
1756-UM020.

Uninstall the ESM
WARNING: If your application requires the ESM to deplete its residual stored
energy to 40 μJoule or less before you transport it into or out of the application,
use the 1756-(SP)ESMNSE(XT) module only. In this case, complete these steps
before you remove the ESM.
1. Turn power off to the chassis.
After you turn power off to the chassis, the controller’s OK status indicator
transitions from green to solid red to OFF.
2. Wait at least 20 minutes for the residual stored energy to decrease to
40 μJoule or less before you remove the ESM.
There is no visual indication of when the 20 minutes has expired. You must
track that time period.
WARNING: When you insert or remove the energy storage module while
backplane power is on, an electrical arc can occur. This could cause an explosion
in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the module
and its mating connector.
IMPORTANT
Before you remove an ESM, make necessary adjustments to your program
to account for potential changes to the WallClockTime attribute.
Consider these points before removing the ESM:
• The following ESM modules may be currently installed in your 1756-L7x
or 1756-L7xXT controller:
–
–
–
–
1756-ESMCAP
1756-ESMNSE
1756-ESMCAPXT
1756-ESMNSEXT
• The 1756-L7x controllers come with the 1756-ESMCAP module already
installed. The 1756-L7xXT extreme temperature controller ships with a
1756-ESMCAPXT module already installed. For more information on
how to use a 1756-ESMNSE, 1756-ESMNRM, 1756-ESMNSEXT, or
1756-ESMNRMXT module, see page 25.
• After the 1756-L7x or 1756-L7xXT controllers lose power, either because
the chassis power is turned off or the controller has been removed from a
powered chassis, do not remove the ESM immediately.
Wait until the controller’s OK status indicator transitions from Green to
Solid Red to OFF before you remove the ESM.
• You can use the 1756-ESMNSE module with a 1756-L73 (8MB) or
smaller memory-sized controller only.

TIP
Connect to the
1756-L7x Controller
When upgrading your 1756-L6x controller firmware, we recommend you use a
network connection other than the serial cable. Serial connections are much
slower than other communication connections.
The controller has a USB port that uses a Type B receptacle. The port is USB 2.0
compatible and runs at 12 Mbps.
To use the USB port of the controller, you must have RSLinx software,
version 2.56 or later, installed on your workstation. Use a USB cable to connect
your workstation to the USB port. With this connection, you can upgrade
firmware and download programs to the controller directly from your
workstation.
ATTENTION: The USB port is intended for temporary local programming
purposes only and not intended for permanent connection. The USB cable is
not to exceed 3.0 m (9.84 ft) and must not contain hubs.
WARNING: Do not use the USB port in hazardous locations.

Use the Mode Switch to Change the Operation Mode
Use the mode switch to change the operation mode. The controller mode switch
provides a mechanical means to enhance controller and control system security.
You must physically move the controller’s mode switch to change its operating
mode from RUN, to REM, or to PROG. When the controller’s mode switch is
set to RUN mode, features like online editing, program downloads, and firmware
upgrades will be prohibited. See Table 5 for a complete list of prohibited features.
The physical mode switch can complement other authorization and
authentication methods that similarly control user-access to the controller, such
as the following:
• Logix CPU Security tool
• FactoryTalk Security service
IMPORTANT
During runtime, we recommend that you place the controller mode switch in
RUN mode and remove the key (if applicable) from the switch. This can help
discourage unauthorized access to the controller or potential tampering with
the controller’s program, configuration, or device firmware. Place the mode
switch in REM or PROG mode during controller commissioning and
maintenance and whenever temporary access is necessary to change the
product’s program, configuration, or firmware.

1. Remove power from the controller.
You can remove power in either of two ways:
• Turn power off to the chassis while the controller is installed in the
chassis.
• Remove the controller from a powered chassis.
Immediately after the controller is no longer powered, the program starts
saving while the OK status indicator is green (this green is a dimmer green
than normal operation), then turns red after program save is complete.
Once the ESM stops operating, it turns off.
The following graphic shows the controller’s OK status indicator.

Clear the Program from On-board NVS Memory
If your application allows it, follow these steps to clear the program from the
1756-L7x controller’s on-board NVS memory.
1. Remove the ESM from the controller.
2. Remove power from the controller.
You can remove power in either of the following two ways:
• Turn power off to the chassis while the controller is installed in the
chassis.
• Remove the controller from a powered chassis.
3. Reinstall the ESM into the controller.
4. Restore power to the controller in one of these two ways:
• If the controller is already installed in the chassis, turn power back onto
the chassis.
• If the controller is not installed into the chassis, reinstall the controller
into the chassis and turn power back onto the chassis.
Estimate the ESM Support
of the WallClockTime
The ESM provides support for the maintenance of the WallClockTime of the
controller when power is not applied. Use this table to estimate the hold-up time
of the ESM based on the temperature of the controller and installed ESM.

1756-BA1 or 1756-BATA Battery Life
To estimate how long a 1756-BA1 or 1756-BATA battery will support controller
memory on 1756-L6x, series A controllers, perform this procedure.
1. Determine the temperature 2.54 cm (1 in.) below the chassis.
2. Determine the weekly percentage of time that the controller is turned on.
EXAMPLE
If a controller is Off either one of these times:
• 8 hr/day during a 5-day work week
• All day Saturday and Sunday
Then the controller is off 52% of the time:
• Total hours per week = 7 x 24 = 168 hrs
• Total off hours per week = (5 days x 8 hr/day) + Saturday +
Sunday = 88 hrs
• Percentage off time = 88/168 = 52%
3. Determine the estimated worst-case battery life before and after the BAT
status indicator turns on.
4. For each year of battery life, decrease the time before the BAT status
indicator turns on by the percentage that is shown in the table.
Do not decrease the time after the BAT status indicator turns on.
IMPORTANT
If the BAT status indicator turns on when you apply power to the
controller, the remaining battery life may be less than this table
indicates. Some of the battery life may have been used up while the
controller was off and unable to turn on the BAT status indicator.

IMPORTANT
The 1756-L7x controllers ship with an SD card installed. We recommend that
you leave the SD card installed, so if a fault occurs, diagnostic data is
automatically written to the card and can be used by Rockwell Automation to
troubleshoot the anomaly.
IMPORTANT
We recommend that you use the SD cards available from Rockwell Automation
(catalog numbers 1784-SD1 or 1784-SD2).
While other SD cards may be used with the controller, Rockwell Automation
has not tested the use of those cards with the controller. If you use an SD card
other than those available from Rockwell Automation, you may experience
data corruption or loss.
Also, SD cards not provided by Rockwell Automation may not have the same
industrial, environmental, and certification ratings as those available from
Rockwell Automation and may not survive in the same industrial environments
as the industrially rated versions available from Rockwell Automation.

Connections over an EtherNet/IP Network
You indirectly determine the number of connections the controller uses by
configuring the controller to communicate with other devices in the system.
Connections are allocations of resources that provide more reliable
communication between devices compared to unconnected messages.
All EtherNet/IP connections are unscheduled. An unscheduled connection is
triggered by the requested packet interval (RPI) for I/O control or the program,
such as a MSG instruction. Unscheduled messaging lets you send and receive data
when needed.

Double Data Rate (DDR) Backplane Communication
DDR communication can be achieved with the 1756-L7x controller. The
following communication modules support DDR when used in conjunction
with the 1756-L7x controller. Minimum series are indicated:
• 1756-EN2T/C
• 1756-EN2TR/B
• 1756-EN2TF/B
• 1756-EN2TXT/C
• 1756-EN3TR/A
• 1756-RM/B
DDR communication is achieved most efficiently when all modules in the
communication path are DDR modules, or, in other words, as a single
conversation (connection) only between DDR modules.
DDR communication is achievable in a chassis with a mix of DDR and nonDDR modules. The DDR communication occurs between the modules that
support it. If non-DDR modules are also in the chassis, communication between
those modules will be at the non-DDR rate.
For example, you could have a chassis with two 1756-L7x controllers in slots 0
and 1 communicating with each other using DDR, and two 1756-L6x controllers
in slots 2 and 3 communicating using non-DDR.
When multicast communication is used within a chassis to multiple modules, the
transmission rate is limited to the slowest module—or at the non-DDR rate.
For example, if a 1756-L7x controller is producing a tag to a 1756-L7x controller
and a 1756-L6x controller on the same multicast connection, it must use the
non-DDR rate.
ControlNet Network
Communication
The ControlNet network is a real-time control network that provides high-speed
transport of both time-critical I/O and interlocking data and messaging data.
This includes uploading and downloading of program and configuration data on
a single physical-media link. The ControlNet network’s highly-efficient data
transfer capability significantly enhances I/O performance and peer-to-peer
communication in any system or application.
The ControlNet network is highly deterministic and repeatable and is unaffected
when devices are connected or disconnected from the network. This quality
results in dependable, synchronized, and coordinated real-time performance.

The ControlNet network often functions as the following:
• A substitute/replacement for the remote I/O (RIO) network because the
ControlNet network adeptly handles large numbers of I/O points
• A backbone for multiple distributed DeviceNet networks
• A peer interlocking network

Communication Networks
Connections over a ControlNet Network
You indirectly determine the number of connections the controller uses by
configuring the controller to communicate with other devices in the system.
Connections are allocations of resources that provide more reliable
communication between devices compared to unconnected messages.
Table 18 - ControlNet Connections
Connection
Definition
Scheduled
(unique to a
ControlNet
network)
A scheduled connection is unique to ControlNet communication. A scheduled connection lets you
send and receive data repeatedly at a predetermined interval, which is the requested packet
interval (RPI). For example, a connection to an I/O module is a scheduled connection because you
repeatedly receive data from the module at a specified interval.
Other scheduled connections include connections to the following:
• Communication devices
• Produced/consumed tags
On a ControlNet network, you must use RSNetWorx for ControlNet software to enable all scheduled
connections and establish a network update time (NUT). Scheduling a connection reserves
network bandwidth specifically to handle the connection.
Unscheduled
An unscheduled connection is a message transfer between devices that is triggered by the
requested packet interval (RPI) or the program, such as a MSG instruction. Unscheduled messaging
lets you send and receive data when you need to:
Unscheduled connections use the remainder of network bandwidth after scheduled connections
are allocated.
ControlNet Module Connections
The 1756-CNB and 1756-CNBR communication modules support 64 CIP
connections over a ControlNet network. However, for optimal performance,
configure a maximum of 48 connections for each module.
The 1756-CN2, 1756-CN2R, and 1756-CN2RXT communication modules
support 128 connections over a ControlNet network, all of which can be
configured without risk of performance degradation.
DeviceNet Network
Communication
The DeviceNet network uses the Common Industrial Protocol (CIP) to provide
the control, configuration, and data collection capabilities for industrial devices.
The DeviceNet network uses the proven Controller Area Network (CAN)
technology, which lowers installation costs and decreases installation time and
costly downtime.
A DeviceNet network provides access to the intelligence present in your devices
by letting you connect devices directly to plant-floor controllers without having
to hard wire each device into an I/O module.
With a ControlLogix system, DeviceNet communication requires the use of a
1756-DNB DeviceNet communication module.

ControlLogix DeviceNet Module Memory
The 1756-DNB module has fixed sections of memory for the input and output
data of the DeviceNet devices on the network. Each device on your network
requires either some input or output memory of the scanner. Some devices both
send and receive data, so they need both input and output memory. The 1756DNB module supports up to add the following:
• 124 DINTs of input data
• 123 DINTs of output data
Data Highway Plus (DH+)
Network Communication
For DH+ network communication, use a 1756-DHRIO module in the
ControlLogix chassis to exchange information between these controllers:
• PLC and SLC controllers
• ControlLogix controllers and PLC or SLC controllers
• ControlLogix controllers
In addition to data exchange between controllers, the DH+ network also
provides the ability to regularly share data both plant-wide and at a cellular level.
You can connect a maximum of 32 stations to a single DH+ link:
• Channel A supports 57.6 Kbps, 115.2 Kbps, and 230.4 Kbps.
• Channel B supports 57.6 Kbps and 115.2 Kbps.

Communicate over a Universal Remote I/O Network
For the controller to control I/O over a universal remote I/O network, you must
complete these tasks.
1. Configure the remote I/O adapter.
2. Lay out the remote I/O network cable.
3. Connect the remote I/O network cable.
4. Configure the scanner channel.
For more information about configuring a remote I/O network with the
1756-RIO or 1756-DHRIO modules, see these publications:
• Data Highway Plus-Remote I/O Communication Interface Module User
Manual, publication 1756-UM514
• ControlLogix Remote I/O Communication Module User Manual,
publication 1756-UM534
As you design your remote I/O network, remember the following:
• All devices connected to a remote I/O network must communicate using
the same communication rate. These rates are available for remote I/O:
– 57.6 Kbps
– 115.2 Kbps
– 230.4 Kbps
• You must assign unique partial and full racks to each channel used in
Remote I/O Scanner mode.
Both channels of a 1756-DHRIO module cannot scan the same partial or
full rack address. Both module channels can communicate to 00...37 octal
or 40...77 octal, but each channel can communicate only with one address
at a time in whichever of these two ranges it falls.

Serial Communication on 1756-L6x Controllers
DF1 Radio Modem Protocol
Your ControlLogix controller includes a driver that allows it to communicate
over the DF1 Radio Modem protocol. This driver implements a protocol,
optimized for use with radio modem networks, that is a hybrid between DF1
full-duplex protocol and DF1 half-duplex protocol, and therefore is not
compatible with either of these protocols.
The DF1 radio modem driver should be used only among devices that
support and are configured for the DF1 Radio Modem protocol.
Additionally, there are some radio modem network configurations that will
not work with the DF1 radio modem driver. In these configurations,
continue to use DF1 half-duplex protocol.

Like DF1 full-duplex protocol, the DF1 radio modem allows any node to initiate
to any other node at any time (that is, if the radio modem network supports fullduplex data-port buffering and radio-transmission collision avoidance). Like
DF1 half-duplex protocol, a node ignores any packets received that have a
destination address other than its own, with the exception of broadcast packets
and passthru packets.
Unlike either DF1 full-duplex or DF1 half-duplex protocols, the DF1 radio
modem protocol does not include ACKs, NAKs, ENQs, or poll packets. Data
integrity is ensured by the CRC checksum.

Serial Communication on 1756-L6x Controllers
Chapter 6
DF1 Radio Modem Advantages
The primary advantage of using the DF1 radio modem protocol for radio
modem networks is in transmission efficiency. Each read/write transaction
(command and reply) requires only one transmission by the initiator (to send the
command) and one transmission by the responder (to return the reply). This
minimizes the number of times the radios need to key-up to transmit, which
maximizes radio life and minimizes radio power consumption.
In contrast, DF1 half-duplex protocol requires five transmissions for the DF1
master to complete a read/write transaction with a DF1 slave—three by the
master and two by the slave.
The DF1 radio modem driver can be used in a pseudo master/slave mode with
any radio modems, as long as the designated master node is the only node
initiating MSG instructions, and as long as only one MSG instruction is triggered
at a time.
For modern serial radio modems that support full-duplex data port buffering and
radio transmission collision avoidance, the DF1 radio modem driver can be used
to set up a masterless peer-to-peer radio network, where any node can initiate
communication to any other node at any time, as long as all of the nodes are
within radio range so that they receive each other’s transmissions.
DF1 Radio Modem Limitations
These considerations must be made if you can implement the new DF1 radio
modem driver in your radio modem network:
• If all of the devices on the network are ControlLogix controllers, you must
configure them with the DF1 radio modem driver via
RSLogix 5000 software, version 17.01.02 or later or Logix Designer
application, version 21.00.00 or later. If not, then make sure that all of the
nodes can support the DF1 radio modem protocol.
• If each node receives the radio transmissions of every other node, being
both within radio transmission/reception range and on a common
receiving frequency (either via a Simplex radio mode or via a single,
common, full-duplex repeater) the radio modems must handle full-duplex
data port buffering and radio transmission collision avoidance.
If this is the case, you can take full advantage of the peer-to-peer message
initiation capability in every node (for example, the ladder logic in any
node can trigger a MSG instruction to any other node at any time).
If not all modems can handle full-duplex data port buffering and radio
transmission collision avoidance, you may still be able to use the DF1 radio
modem driver, but only if you limit MSG instruction initiation to a single
master node whose transmission can be received by every other node.
Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
103
Chapter 6
Serial Communication on 1756-L6x Controllers
• If not all nodes receive the radio transmission of every other node, you
may still be able to use the DF1 radio modem driver, but only if you limit
MSG instruction initiation to the node connected to the master radio
modem whose transmissions can be received by every other radio modem
in the network.
• You can take advantage of the ControlLogix controller channel-to-channel
passthru to remotely program the other nodes via RSLinx Classic and
Logix Designer applications running on a personal computer connected to
a local ControlLogix controller via DH-485, DH+, or Ethernet network.

To optimize network performance, assign node addresses in sequential order. Initiators, such as personal computers, should be assigned the
lowest address numbers to minimize the time required to initialize the network.
Error Detection
Click one of the radio buttons to specify the error detection scheme used for all messages.
• BCC - the processor sends and accepts messages that end with a BCC byte.
• CRC - the processor sends and accepts messages with a 2 byte CRC.
Enable Store and Forward
Check ’Enable Store and Forward’ if you want to enable the store and forward functionality. When enabled, the destination address of any
received message is compared to the Store and Forward tag table. If there is a match, the message is then forwarded (re-broadcasted) out the
port.
From the Store and Forward Tag pull-down menu, choose an integer (INT[16]) tag.
Each bit represents a station address. If this controller reads a message destined for a station that has its bit set in this table, it forwards the
message.
DF1 Slave Protocol
With the DF1 slave protocol, a controller uses DF1 half-duplex protocol. One
node is designated as the master and it controls who has access to the link. All the
other nodes are slave stations and must wait for permission from the master
before transmitting.
Make these considerations when using the DF1 Slave protocol:
• If multiple slave stations are used on the network, link slave stations by
using modems or line drivers to the master.
• If you are using a single slave station on the network, you do not need a
modem to connect the slave station to the master.
• Control parameters can be configured without handshaking.
• 2...255 nodes can be connected to a single link.

Serial Communication on 1756-L6x Controllers
DH-485 Protocol
Chapter 6
The controller can send and receive messages to and from other controllers on a
DH-485 network. The DH-485 connection supports remote programming and
monitoring via the Logix Designer application. However, excessive traffic over a
DH-485 connection can adversely affect overall controller performance and lead
to timeouts and decreased performance of the configuration.
You can also use a 1756-DH485 module to connect the ControlLogix chassis to a
DH-485 network with multiple controllers. For more information, see the
ControlLogix DH-485 Communication Module User Manual, publication
1756-UM532.
IMPORTANT
Use Logix5000 controllers on DH-485 networks only when you want to add
controllers to an existing DH-485 network.
For new applications with Logix5000 controllers, we recommend that you
use networks in the NetLinx open architecture.
The DH-485 protocol uses RS-485 half-duplex as its physical interface. RS-485
is a definition of electrical characteristics, not a protocol. You can configure the
RS-232 port of the ControlLogix controller to act as a DH-485 interface.
To connect the controller to the DH-485 network, you must use these
components:
• A 1761-NET-AIC converter (two controllers can be connected to one
converter)
• An RS-232 cable (catalog number 1756-CP3 or 1747-CP3) for each
controller to connect to the converter

ASCII Protocol
Chapter 6
When you configure the serial port for User mode and the ASCII protocol, you
can use it to do the following:
• Read ASCII characters from a weigh scale module or bar code reader.
• Send and receive messages from an ASCII-triggered device, such as a
MessageView™ terminal.
After you configure the controller for use with the ASCII protocol, program the
controller using the ASCII instructions. Reference the Logix5000 Controllers
General Instruction Reference Manual, publication 1756-RM003, for
information about the ASCII instructions.

Broadcast Messages over
a Serial Port
You can broadcast messages over a serial port connection from a master controller
to all of its slave controllers by using several communication protocols. These
protocols include the following:
• DF1 Master
• DF1 Radio Modem
• DF1 Slave
Broadcasting over a serial port is achieved by using the ‘message’ tag. Because
messages are sent to receiving controllers, only the ‘write’ type messages can be
used for broadcasting.
The broadcast feature can be set up by using ladder logic or structured text. The
broadcast feature can also be set by modifying the path value of a message tag in
the tag editor.
To configure and program the controller to broadcast messages via the serial port,
complete these procedures:
• Configure Controller Serial Port Properties on page 110
• Program the Message Instruction on page 111
For these procedure examples, ladder logic programming is used.

The system-shared tags are explained in this table.
Table 26 - Produced and Consumed Tag Definitions
Tag
Definition
Produced tag
A tag that a controller makes available for use by other controllers. Multiple controllers
can simultaneously consume (receive) the data. A produced tag sends its data to one or
more consumed tags (consumers) without using logic.
Consumed tag
A tag that receives the data of a produced tag. The data type of the consumed tag must
match the data type (including any array dimensions) of the produced tag. The RPI of
the consumed tag determines the period at which the data updates.
For two controllers to share produced or consumed tags, both must be attached
to the same network. You cannot bridge produced and consumed tags over two
networks.
Produced and consumed tags use connections of both the controller and the
communication modules being used. For a ControlNet network, produced and
consumed tags use scheduled connections.
Connection Requirements of a Produced or Consumed Tag
Produced and consumed tags each require connections. As you increase the
number of controllers that can consume a produced tag, you also reduce the
number of connections the controller has available for other operations, like
communication and I/O.
IMPORTANT
114
If a consumed-tag connection fails, all of the other tags being consumed from
that remote controller stop receiving new data.

EXAMPLE
Communication
Calculations of connections for produced or consumed tags:
• A ControlLogix controller producing 4 tags for 1 controller uses 8
connections.
Each tag uses 2 connections (1 consumer + 1 = 2).
2 connections per tag x 4 tags = 8 connections.
• Consuming 4 tags from a controller uses 4 connections (1 connection per
tag x 4 tags = 4 connections).
The number of available connections limits the number of tags that can be
produced or consumed. If the controller uses all of its connections for I/O and
communication devices, no connections are left for produced and consumed tags.

Manage Controller Communication
Send and Receive Messages
Messages transfer data to other devices, such as other controllers or operator
interfaces. The MSG instruction is a ladder logic output instruction that
asynchronously reads or writes a block of data to or from another module over
the backplane or a network. The size of the instruction depends on the data types
and message command programmed by the user.
Messages use connection resources to send or receive data. Messages can leave the
connection open (cache) or closed when the message is done transmitting.
Each message uses one connection out of the controller, regardless of how many
devices are in the message path. To conserve connections, configure one message
to read from or write to multiple devices.

• Logix5000 Controllers General Instructions, publication 1756-RM003
Determine Whether to Cache Message Connections
When you configure a MSG instruction, you can choose whether to cache the
connection. Use this table to determine if you should cache connections.
Table 30 - Options for Caching Connections
If the message executes
Then
Repeatedly
Cache the connection.
This keeps the connection open and optimizes execution time. Opening a
connection each time the message executes increases execution time.
Infrequently
Do not cache the connection.
This closes the connection upon completion of the message, which frees up that
connection for other uses.
TIP
116
Cached connections transfer data faster than uncached connections.The
controller only supports 32 cached messages.

Reconfigure an I/O Module
Chapter 8
If an I/O module supports reconfiguration, you can reconfigure the module via
the following:
• The Module Properties dialog box in the I/O Configuration folder
• A MSG instruction in program logic.
IMPORTANT
Use care when changing the configuration of an I/O module. You could
inadvertently cause the I/O module to operate incorrectly.
Use a MSG instruction of type Module Reconfigure to send new configuration
information to an I/O module. During the reconfiguration, consider the
following:
• Input modules continue to send input data to the controller
• Output modules continue to control their output devices
Reconfigure an I/O Module via the Module Properties
To reconfigure an I/O module using the module properties, right-click the
module in the I/O Configuration tree and choose Properties. Then, edit the
properties you need to change and click Apply.

Chapter 8
I/O Modules
Reconfigure an I/O Module via a Message Instruction
To reconfigure an I/O module via a message instruction, use this procedure.
1. Set the required member of the configuration tag of the module to the new
value.
2. Send a Module Reconfigure message to the module.
EXAMPLE
Reconfigure an I/O module
When reconfigure[5] is on, the MOV instruction sets the high alarm to 60 for the local module in slot 4. The Module
Reconfigure message then sends the new alarm value to the module. The ONS instruction prevents the rung from sending
multiple messages to the module while the reconfigure[5] is on.
For more information about using Message instructions, see the Logix5000
Controllers General Instruction Reference Manual, publication 1756-RM003.
Add to the I/O Configuration
While Online
With RSLogix 5000 software, version 15.02.00 or later, and Logix Designer
application, version 21.00.00 or later, you can add I/O and other devices to the
controller configuration while you are online and in Run mode.
The specific modules and devices you can add while online depends on the
version of the software you are using. Later versions have more modules and
devices that can be added while online.
You can add these modules and devices to the local or remote chassis via the
unscheduled portion of a ControlNet network or via an EtherNet/IP network.
For more information about adding to the I/O Configuration while online, see

Online Additions - ControlNet Considerations
ControlNet considerations that must be made depend upon the ControlLogix
ControlNet modules you are using.
1756-CNB and 1756-CNBR Modules
When you add I/O to the ControlNet network via the 1756-CNB or
1756-CNBR modules while online, these considerations must be made:
• Digital I/O modules can be added as rack-optimized connections if the
parent module is already configured with rack-optimized connections.
TIP
While you can add a new digital I/O module to an existing rack-optimized
connection, you cannot add rack-optimized connections while online.
• Digital I/O modules can also be added as direct connections.
• Analog I/O modules can be added only as direct connections.
• Disable the Change of State (COS) feature on digital input modules
because it can cause inputs to be sent more quickly than the RPI.
Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
135
Chapter 8
I/O Modules
• If you plan to add large amounts of I/O to the ControlNet network,
dedicate one ControlNet network for I/O. For the dedicated
ControlNet network, verify that there is little or none of the following:
– HMI traffic
– MSG traffic
– Programming workstations
• Requested Packet Intervals (RPIs) faster than 25 ms for unscheduled
modules can overload the 1756-CNB or 1756-CNBR communication
module. To avoid the overload, make these considerations:
– Use a NUT of 10 ms or more.
– Keep the SMAX and UMAX values as small as possible.
• If the module has a Real Time Sample (RTS), it should be disabled or set
to a rate that is greater than the RPI.
• You can add I/O modules until you reach these limits:
– 75% of CPU utilization of the 1756-CNB or 1756-CNBR
communication module.
– Plan for a CPU-use increase of 1...4% of the 1756-CNB or
1756-CNBR module for each I/O module you add, depending on the
RPI.
– 48 connections on the 1756-CNB or 1756-CNBR communication
module.
– Less than 400,000 unscheduled bytes per second are displayed in
RSNetWorx for ControlNet software after the network has been
scheduled.
1756-CN2, 1756-CN2R, 1756-CN2RXT Modules
The use of 1756-CN2/B, 1756-CN2R/B, and 1756-CN2RXT modules
provides increased capacity for adding I/O while online compared to 1756-CNB
or 1756-CNBR modules. With this increased capacity, you can easily add I/O
and increase ControlNet connections used with significantly less impact on the
overall system.

Because of the increased performance provided by the 1756-CN2, 1756-CN2R,
and 1756-CN2RXT modules, many of the considerations that must be made
with the 1756-CNB and 1756-CNBR modules are not applicable. With the
1756-CN2, 1756-CN2R, and 1756-CN2RXT modules, you can add I/O while
online as long as you use reasonable RPI settings and remain within the CPU
limitations of the ControlNet module.
When adding to the I/O Configuration with 1756-CN2, 1756-CN2R, and
1756-CN2RXT modules, make these considerations:
• Digital I/O modules can be added as rack-optimized connections if the
parent module is already configured with rack-optimized connections.
TIP
While you can add a new digital I/O module to an existing rackoptimized connection, you cannot add rack-optimized connections
while online.
• Digital I/O modules can also be added as direct connections.

Online Additions—EtherNet/IP Considerations
When you add I/O modules to the EtherNet/IP network, make these
considerations:
• The EtherNet/IP I/O modules you add can be added as these connection
types:
– Rack-optimized connections, including new and existing connections
– Direct connections
• You can add I/O modules until you reach the limits of the communication
module’s connections.

The controller provides a set of motion control instructions for your axes:
• The controller uses these instructions just like the rest of the Logix5000
instructions.
• Each motion instruction works on one or more axes.
• Each motion instruction needs a motion control tag. The tag uses a
MOTION_INSTRUCTION data type and stores the instruction’s

Example
In this example, a simple ladder diagram that homes, jogs, and moves an axis.
If Initialize_Pushbutton = on and the axis = off (My_Axis_X.ServoActionStatus = off) then
the MSO instruction turns on the axis.
If Home_Pushbutton = on and the axis hasn’t been homed (My_Axis_X.AxisHomedStatus = off) then
the MAH instruction homes the axis.

If Jog_Pushbutton = on and the axis = on (My_Axis_X.ServoActionStatus = on) then
the MAJ instruction jogs the axis forward at 8 units/second.
If Jog_Pushbutton = off then
the MAS instruction stops the axis at 100 units/.second2.
Make sure that Change Decel is Yes. Otherwise, the axis decelerates at its maximum speed.
If Move_Command = on and the axis = on (My_Axis_X.ServoActionStatus = on) then
the MAM instruction moves the axis. The axis moves to the position of 10 units at 1 unit/second.

A Logix5000 controller lets you use multiple tasks to schedule and prioritize the
execution of your programs based on specific criteria. This multitasking allocates
the controller’s processing time among the different operations in your
application:
• The controller executes only one task at a time.
• One task can interrupt another’s execution and take control.
• In any given task, multiple programs may be used. However, only one
program executes at a time.

A task provides scheduling and priority information for a set of one or more
programs. Configure tasks as continuous, periodic, or event using the Task
Properties dialog box.
Figure 30 - Configuring the Task Type
This table explains the types of tasks you can configure.
Table 36 - Task Types and Execution Frequency
Task Type
Task Execution
Description
Continuous
All of the time
The continuous task runs in the background. Any CPU time not allocated to other operations (such as motion,
communication, and other tasks) is used to execute the programs in the continuous task.
• The continuous task runs constantly. When the continuous task completes a full scan, it restarts immediately.
• A project does not require a continuous task. If used, there can be only one continuous task.
Periodic
• At a set interval, such as every
100 ms
• Multiple times within the scan
of your other logic
A periodic task performs a function at a specific interval.
• Whenever the time for the periodic task expires, the task interrupts any lower priority tasks, executes once, and then
returns control to where the previous task left off.
• You can configure the time period from 0.1...2,000,000.00 ms. The default is 10 ms. It is also controller and configuration
dependent.
• The performance of a periodic task depends on the type of Logix5000 controller and on the logic in the task.
Event
Immediately when an event occurs
An event task performs a function only when a specific event (trigger) occurs. The trigger for the event task can be the
following:
• Module input data change of state
• A consumed tag trigger
• An EVENT instruction
• An axis trigger
• A motion event trigger
The ControlLogix controller supports up to 32 tasks, only one of which can be
continuous.
A task can have up to 100 separate programs, each with its own executable
routines and program-scoped tags. Once a task is triggered (activated), all the
programs assigned to the task execute in the order in which they are grouped.
Programs can appear only once in the Controller Organizer and cannot be shared
by multiple tasks.

Chapter 10
Task Priority
Each task in the controller has a priority level. The operating system uses the
priority level to determine which task to execute when multiple tasks are
triggered. A higher priority task will interrupt any lower priority task. The
continuous task has the lowest priority and is always interrupted by a periodic or
event task.
You can configure periodic and event tasks to execute from the lowest priority of
15 up to the highest priority of 1. Configure the task priority using the Task
Properties dialog box.

Programs
The controller operating system is a preemptive multitasking system that is IEC
1131-3 compliant. This system provides the following:
• Programs to group data and logic
• Routines to encapsulate executable code written in a single programming
language
Each program contains the following:
• Program tags
• A main executable routine
• Other routines
• An optional fault routine

Scheduled and Unscheduled Programs
The scheduled programs within a task execute to completion from first to last.
Programs that aren’t attached to any task show up as unscheduled programs.
Unscheduled programs within a task are downloaded to the controller with the
entire project. The controller verifies unscheduled programs but does not execute
them.
You must schedule a program within a task before the controller can scan the
program. To schedule an unscheduled program, use the Program/Phase Schedule
tab of the Task Properties dialog box.

Routines
A routine is a set of logic instructions in a single programming language, such as
Ladder Diagram (ladder logic). Routines provide the executable code for the
project in a controller. A routine is similar to a program file or subroutine in a
PLC or SLC processor.
Each program has a main routine. This is the first routine to execute when the
controller triggers the associated task and calls the associated program. Use logic,
such as the Jump to Subroutine ( JSR) instruction, to call other routines.
You can also specify an optional program fault routine. The controller executes
this routine if it encounters an instruction-execution fault within any of the
routines in the associated program.

With a Logix5000 controller, you use a tag (alphanumeric name) to address data
(variables). In Logix5000 controllers, there is no fixed, numeric format. The tag
name identifies the data and lets you do the following:
• Organize your data to mirror your machinery.
• Document your application as you develop it.
Tags
This example shows data tags created within the scope of the Main Program of
the controller.

Extended Properties
The Extended Properties feature lets you define additional information, such as
limits, engineering units, or state identifiers, for various components within your
controller project.
Component
Extended Properties
Tag
In the tag editor, add extended properties to a tag.
User-defined data type
In the data type editor, add extended properties to data types.
Add-On Instructions
In the properties associated with the Add-On Instruction definition, add
extended properties to Add-On Instructions.
Pass-through behavior is the ability to assign extended properties at a higher level
of a structure or Add-On Instruction and have that extended property
automatically available for all members. Pass-through behavior is available for
descriptions, state identifiers, and engineering units and is user configurable.
Configure pass-through behavior on the Project tab of the Controller Properties
dialog box. If you choose not to show pass-through properties, then only
extended properties that have been configured for a given component are
displayed.
Pass-through behavior is not available for limits.When an instance of a tag is
created, if limits are associated with the data type, the instance is copied.
You need to know which tags have limits associated with them as there is no
indication in the tag browser that extended properties are defined for a tag. If,
however, you try to use extended properties that have not been defined for a tag,
the editors show a visual indication and the routine does not verify.
Access Extended Properties in Logic
You can access limits defined on tags by using the .@Min and .@Max syntax:
• You cannot write to extended properties values in logic.
• To use extended tag properties in an Add-On Instruction, you must pass
them in as input operands to the Add-On Instruction.
• Aliases to tags that have extended properties cannot access the extended
properties in logic.
• Limits can be configured for input and output parameters in Add-On
Instructions. However, limits cannot be defined on an InOut parameter of
an Add-On Instruction.
• Limits cannot be accessed inside Add-On Instruction logic. Limits are for
use by HMI applications only.

Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
Develop Applications
Chapter 10
If an array tag is using indirect addressing to access limits in logic, the following
conditions apply:
• If the array tag has limits configured, the extended properties are applied to
any array element that does not explicitly have that particular extended
property configured. For example, if the array tag MyArray has Max
configured to 100, then any element of the array that does not have Max
configured inherits the value of 100 when being used in logic. However, it
will not be visible to you that the value inherited from MyArray is
configured in the tag properties.
• At least one array element must a limit configured for indirectly referenced
array logic to verify. For example, if MyArray[x].@Max is being used in
logic, at least one array element of MyArray[] must have Max extended
property configured if Max is not configured by MyArray.
• Under the following circumstances a data type default value is used:
– Array is accessed programmatically with indirect reference.
– Array tag does not have the extended property configured.
– A member of an array does not have the extended property configured.
For example, for an array of SINT type, when max limit is called in logic
for a member, the value 127 will be used.
If an array element is directly accessed, the element has to have the extended
property defined. If not verification will fail.

With RSLogix 5000 software, version 16.03.00 or later, and Logix Designer
application, version 21.00.00 or later, you can design and configure sets of
commonly used instructions to increase project consistency. Similar to the
built-in instructions contained in Logix5000 controllers, these instructions you
create are called Add-On Instructions. Add-On Instructions reuse common
control algorithms. With them, you can do the following:
• Ease maintenance by animating logic for a single instance.
• Protect intellectual property with locking instructions.
• Reduce documentation development time.
Add-On Instructions
You can use Add-On Instructions across multiple projects. You can define your
instructions, obtain them from somebody else, or copy them from another
project.
This table explains some of the capabilities and advantages of use Add-On
Instructions.
Table 38 - Add-On Instruction Capabilities
Capability
Description
Save Time
With Add-On Instructions, you can combine your most commonly used logic into sets of reusable instructions. You save time when you
create instructions for your projects and then share them with others. Add-On Instructions increase project consistency because
commonly used algorithms all work in the same manner, regardless of who implements the project.
Use Standard Editors
You create Add-On Instructions by using one of three programming editors:
• Relay Ladder
• Function Block Diagram
• Structured Text
Export Add-On Instructions
You can export Add-On Instructions to other projects as well as copy and paste them from one project to another. Give each instruction
a unique name so that you don’t accidentally overwrite another instruction of the same name.
Use Context Views
Context views let you visualize an instruction’s logic for a specific instant, simplifying online troubleshooting of your Add-On
Instructions. Each instruction contains a revision, a change history, and an auto-generated help page.
Create Custom Help
When you create an instruction, you enter information for the description fields. This information then becomes custom Help.
Apply Source Protection
As the creator of Add-On Instructions, you can limit users of your instructions to read-only access, or you can bar access to the internal
logic or local parameters used by the instructions. This source protection lets you prevent unwanted changes to your instructions and
protects your intellectual property.
Once defined in a project, Add-On Instructions behave similarly to the built-in
instructions in Logix5000 controllers. They appear on the instruction tool bar
for easy access along with internal instructions.

Monitoring Controller Status
The ControlLogix controller uses Get System Value (GSV) and Set System Value
(SSV) instructions to get and set (change) controller data. The controller stores
system data in objects. There is no status file, as in the PLC-5 processor.
The GSV instruction retrieves the specified information and places it in the
destination. The SSV instruction sets the specified attribute with data from the
source. Both instructions are available from the Input/Output tab of the
Instruction toolbar.
Figure 39 - GSV and SSV Instructions for Monitoring and Setting Attributes
158
Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
Develop Applications
Chapter 10
When you add a GSV/SSV instruction to the program, the valid object classes,
object names, and attribute names for the instruction are shown. For the GSV
instruction, you can get values for all the available attributes. For the SSV
instruction, only the attributes you can set are shown.
Some object types appear repeatedly, so you may have to specify the object name.
For example, there can be several tasks in your application. Each task has its own
Task object that you access by the task name.
There are several objects and attributes that you can use the GSV and SSV
instructions to monitor and set the system. For more information about GSV
instructions, SSV instructions, objects, and attributes see the Logix5000
Controllers General Instructions Reference Manual, publication 1756-RM003.
Monitoring I/O Connections
If communication with a device in the controller’s I/O configuration does not
occur in an application-specific period of time, the communication times out and
the controller produces warnings.
The minimum timeout period that, once expired without communication, causes
a timeout is 100 ms. The timeout period may be greater, depending on the
application’s RPI. For example, if your application uses the default RPI = 20 ms,
the timeout period is 160 ms.
For more information on how to determine the time for your application, search
the Rockwell Automation Knowledgebase for answer ID 38535. The document
is available at http://www.rockwellautomation.com/knowledgebase.
When a timeout does occur, the controller produces these warnings;
• An I/O fault status code is indicated on the status display of the 1756-L7x
controller.
• The I/O status indicator on the front of the 1756-L6x controller flashes
green.
• A ! shows over the I/O configuration folder and over the devices that
have timed out.
• A module fault code is produced, which you can access via the following:
– The Module Properties dialog box
– A GSV instruction
For more information about I/O faults, see the Major, Minor, and I/O Faults

Determine if I/O Communication has Timed Out
This example can be used with either the 1756-L7x or 1756-L6x controllers:
• The GSV instruction gets the status of the I/O status indicator (via the
LEDStatus attribute of the Module object) and stores it in the
IO_LED tag.
• IO_LED is a DINT tag that stores the status of the I/O status indicator or
status display on the front of the controller.
• If IO_LED equals 2, than at least one I/O connection has been lost and
the Fault_Alert is set.
Figure 40 - GSV Used to Identify I/O Timeout
For more information about attributes available with the Module object, see the
Logix5000 Controllers General Instructions Reference Manual, publication
1756-RM003.
Determine if I/O Communication to a Specific I/O Module has
Timed Out
If communication times out with a device (module) in the I/O configuration of
the controller, the controller produces a fault code and fault information for the
module. You can use GSV instructions to get fault code and information via the
FaultCode and FaultInfo attributes of the Module object.
For more information about attributes available with the Module object, see the

Interrupt the Execution of Logic and Execute the Fault Handler
Depending on your application, you might want an I/O connection error to
cause the Controller Fault Handler to execute. To do so, set the module property
that causes a major fault to result from an I/O connection error. The major fault
then causes the execution of the Controller Fault Handler.
First, develop a routine in the Controller Fault Handler that can respond to I/O
connection faults. Then, in the Module Properties dialog box of the I/O module
or parent communication module, check Major Fault On Controller If
Connection Fails While in Run Mode.

System Overhead Time Slice
The controller communicates with other devices at either a specified rate
(scheduled) or when there is processing time available to service the
communication.
The system overhead time slice specifies the percentage of time a controller
devotes to service communication. If you have a continuous task, the system
overhead time slice entered on the Advanced tab of the Controller Properties
dialog box specifies the continuous task/service communication ratio. However,
if there is no continuous task, the overhead time slice has no effect.
The table shows the ratio between the continuous task and service
communication at various system overhead time slices for RSLogix 5000, version
16.03.00 or later, and Logix Designer version 21.00.00 or later.

returns to the continuous task.
• The Reserve for System Task radio button allocates the entire 1 ms of
the system overhead time slice whether the controller has
communication or background tasks to perform before returning back
to the continuous task. This lets you simulate a communication load on
the controller during design and programming before HMIs, controller

Description
Equipment phase
• As with a program, an equipment phase is run in a task and is given a set of routines and
tags.
• Unlike a program, an equipment phase runs by a state model and lets you do one activity.
State model
• A state model divides the operating cycle of your equipment into a series of states. Each
state is an instance in the operation of the equipment, the actions, or conditions of the
equipment at a given time.
• The state model of an equipment phase resembles that of the S88 and PackML state
models.
State machine
An equipment phase includes an embedded state machine that does the following:
• Calls the routine associated with an active state
• Manages the transitions between states with minimal coding
• Makes sure that the equipment goes from state to state along an allowable path
PHASE tag
When you add an equipment phase, the application creates a tag for the equipment phase.
The tag uses the PHASE data type.

How does the equipment get ready to run?
Running
What does the equipment do to make product?
Holding
How does the equipment temporarily stop making product without making scrap?
Restarting
How does the equipment resume production after holding?
Stopping
What happens during a normal shutdown?
Aborting
How does the equipment shut down if a fault or failure occurs?
How Equipment Changes States
The state model’s arrows show the states through which your equipment
progresses:
• Each arrow is called a transition.
• A state model lets the equipment make only certain transitions. This
restriction standardizes the equipment’s behavior so that other equipment
using the same model will behave the same way.

Description
Command
A command tells the equipment to do something. For example, the operator pushes the start
button to begin production and the stop button to halt production.
The PhaseManager tool uses these commands:
Reset
Stop
Restart
Start
Hold
Abort
Done
Equipment goes to a waiting state when it is finished with what it is doing. You do not give the
equipment a command. Instead, you set up your code to signal when the phase state is
finished.
Fault
A fault tells you that something out of the ordinary has happened. You set up your code to look
for faults and take action if it finds any. If you want to shut down your equipment as quickly as
possible when it detects a fault, set up your code to look for that fault and give the abort
command if it finds it.
Manually Change States
You can manually change an equipment phase. To manually change a
PhaseManager state, perform this procedure.
1. Open the Equipment Phase Monitor.
2. Take ownership of the equipment phase by clicking Owners and clicking
Yes.
3. Click the command that initiates the state you need (for example, Start or
Reset).
4. After you have finished manually changing the state, click Owners to
release your ownership.

Redundancy provides more system availability by switching control to a
secondary controller chassis if a fault occurs in the primary controller chassis.
The redundant system switches control from the primary to the secondary when
these faults occur:
• Power loss to primary chassis
• Hardware or firmware failure of any module in the primary chassis
• A major fault in the user program on the primary controller
• Loss of communication between the primary chassis and remote
ControlNet or EtherNet/IP modules
• Disconnection of an Ethernet patch cable from an EtherNet/IP
communication module in the primary chassis
• Removal or insertion of any module in the primary chassis
• A user command that causes a switchover

I/O can be connected via an EtherNet/IP network beginning with Enhanced Redundancy System revision 19.50.
Redundancy requires no additional programming and is transparent to any
devices connected over an EtherNet/IP or ControlNet network.
Redundancy modules placed in each redundant chassis maintain the
communication between the redundant chassis.
Depending on how you organize your project, outputs may or may not
experience a change in state (bump) during a switchover:
• During the switchover, outputs that are controlled by the highest priority
task will experience a bumpless switchover. For example, outputs will not
revert to a previous state.
• Outputs in lower priority tasks may experience a change of state.

Chapter 12
Redundant Systems
System Considerations
When you are configuring a redundant ControlLogix system, these
considerations specific to modules in the redundant chassis must be made.
Items in Primary and
Secondary Chassis
Consideration
ControlLogix controller
• When configured for redundancy, the secondary controller automatically receives
and buffers data.
• A redundant controller uses twice as much data memory and I/O memory space as
a nonredundant controller.
• A redundant controller has a significantly longer scan time than a nonredundant
controller.
• The ControlLogix Enhanced Redundancy User Manual, publication 1756-UM535,
provides detailed information about minimizing the scan time impact.
• You do not need a redundancy-specific version of Logix Designer software, but it
must match your Enhanced Redundancy System revision level.
Communication modules
• In an enhanced redundancy system, as many as seven communication modules can
reside in a controller chassis in any combination of EtherNet/IP modules and
ControlNet modules.
• To connect to other networks, bridge through another ControlLogix chassis outside
the redundant system.
• For best results, use a separate networks for HMI and I/O communication.
I/O modules
• All I/O is remote from the redundant controller chassis.
• Beginning with Enhanced Redundancy System revision 19.50, EtherNet/IP
networks in redundant systems can be used for remote I/O or produced/consumed
data.
Redundant power supplies
The 1756-PA75R and 1756-PB75R redundant power supplies provide reliable chassis
power.
Redundant ControlNet media
Redundant media provide more reliable ControlNet communication.
For complete information about designing and planning modules for use in your
redundant ControlLogix chassis, see the ControlLogix Enhanced Redundancy
User Manual, publication 1756-UM535.

(1) Availability of some features supported in enhanced redundancy are dependent on the system revision used. For more information,
see ControlLogix Enhanced Redundancy System User Manual, publication 1756-UM535.
Build a Redundant System
To build a typical redundant system, perform this procedure.
1. Install a ControlLogix chassis and power supply.
2. To the primary chassis, add 1756-L6x or 1756-L7x controllers.
Note that you cannot mix 1756-L6x and 1756-L7x controllers in the same
chassis.
3. Add one or more ControlNet or EtherNet/IP communication modules.
4. Add one redundancy module.
5. Set up a secondary chassis that is identical to the primary chassis.
IMPORTANT
Components in the redundant chassis pair must be identical in
module configuration.
6. Connect the redundancy modules in both chassis.
7. Add I/O modules to ControlNet or EtherNet/IP networks.
8. Add operator interfaces to ControlNet or EtherNet/IP networks.
For detailed information on designing and building an enhanced redundant
system, refer to the ControlLogix Enhanced Redundancy System User Manual,
publication 1756-UM535.

Chapter 12
Redundant Systems
ControlNet Considerations
in Redundant Systems
You can have as many as seven ControlNet communication modules in a
redundant chassis.
IMPORTANT
With each ControlNet network, you must have at least two nodes external
to the redundant controller chassis to avoid timeouts on switchover.
The lowest node of each ControlNet network must be outside the
redundant controller chassis.
For information on ControlNet considerations for enhanced redundant systems,
refer to the ControlLogix Enhanced Redundancy System User Manual,
publication 1756-UM535.
EtherNet/IP Considerations
in Redundant Systems
You can have as many as seven EtherNet/IP modules in the redundant chassis.
In a redundant system, you can use EtherNet/IP for HMI communication or
inter-controller messaging. HMI can communicate directly to with the primary
controller. You no longer need RSLinx Alias Topics.
ControlLogix redundancy supports EtherNet/IP for I/O control or producing
and consuming data beginning with Enhanced Redundancy System revision
19.50, and can be used for the following:
• 1715 Redundant I/O
• Remote I/O modules
• HMI connections to the primary controller
• Producing and consuming data
For information on EtherNet/IP considerations for enhanced redundant systems,
refer to the ControlLogix Enhanced Redundancy System User Manual,
publication 1756-UM535.
IP Address Swapping
Firmware revision 13, and later, supports IP address swapping in redundant
systems. With IP address swapping, you configure the primary and secondary
EtherNet/IP modules with the same IP address. The primary EtherNet/IP
module takes the IP address; the secondary module takes that address plus one in
the last address segment.
On a switchover, the EtherNet/IP modules swap IP addresses. HMI devices
automatically continue to communicate with the new primary controller because
the IP addresses were swapped. Because of the way EtherNet/IP modules work,
during a switchover, communication between the controller and an HMI device
halts for several seconds, typically less than a minute.
176
Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
Redundant Systems
Redundancy and Scan Time
Chapter 12
At the end of every program, the primary controller synchronizes and crossloads
fresh data to the secondary controller. This keeps the secondary controller up-todate and ready to take over. It also increases the scan time when compared to a
nonredundant system.
The amount of time a crossload consumes depends on how much data the
primary controller has to crossload:
• The primary controller synchronizes and crossloads any tag to which an
instruction wrote a value, even the same value, since the last crossload.
• Crossloading also requires a small amount of overhead time (1 ms per
crossload) to tell the secondary controller which program the primary
controller is executing.
Redundancy firmware revision 16.53, or later, provides the ability to limit which
programs are followed by synchronization and data crossloading. In many
applications, changing this can reduce the overall impact to the task scan time by
reducing the number of times a data area is synchronized. Removing a
synchronization point results in 1 ms of overhead time saved, in addition to any
time that was used to crossload the data.
For complete details about the scan time of a redundant system, see the
ControlLogix Enhanced Redundancy System User Manual, publication
1756-UM535.

Typical SIL2 Configurations

Certain catalog numbers of the ControlLogix system are type-approved and
certified for use in SIL2 applications according to these standards:
• IEC 61508
• IEC 61511
Approval requirements are based on the standards current at the time of
certification.
These requirements consist of mean time between failures (MTBF), probability
of failure, failure rates, diagnostic coverage and safe failure fractions that fulfill
SIL2 criteria. The results make the ControlLogix system suitable up to, and
including, SIL2. When the ControlLogix system is in the Maintenance or
Programming mode, the user is responsible for maintaining a safe state.
The TÜV Rheinland Group has approved the ControlLogix system for use in up
to, and including, SIL 2 safety related applications in which the de-energized
state is typically considered to be the safe state.
In addition, specific configuration and programming considerations described in
the Using ControlLogix in SIL2 Applications Safety Reference Manual,
publication 1756-RM001, must be made.
Programming and Debugging Tool (PADT)
For support in creation of programs, the Programming and Debugging Tool
(PADT) is required. The PADT for the ControlLogix system is the Logix
Designer application, per IEC 61131-3, and the Using ControlLogix in SIL2

levels of availability that can be achieved by using various ControlLogix system
configurations are referred to as fail-safe, high-availability, or fault-tolerant.
This table lists each system configuration and the hardware that is part of the
system’s safety loop.

Fail-safe Configuration
In a fail-safe configuration, the hardware used in the safety loop is not redundant.
Therefore, if a fault occurs anywhere in the SIL2 system, the system is
programmed to fail to safe.
The failure to safe is typically an emergency shutdown where all outputs are deenergized.

ESM Incompatible
The ESM is incompatible with the memory size of the controller.
Replace the incompatible ESM with a compatible ESM.
ESM Hardware Failure
A failure with the ESM has occurred and the controller is incapable of saving of the program in the event of a powerdown.
Replace the ESM before removing power to the controller so the controller program is saved.
ESM Energy Low
The capacitor-based ESM does not have sufficient energy to enable the controller to save the program in the event of a powerdown.
Replace the ESM.
ESM Charging
The capacitor-based ESM is charging.
Do not remove power until charging is complete.

201
The electronic keying feature automatically compares the expected module, as
shown in the RSLogix 5000 I/O Configuration tree, to the physical module
before I/O communication begins. You can use electronic keying to help prevent
communication to a module that does not match the type and revision expected.
For each module in the I/O Configuration tree, the user-selected keying option
determines if, and how, an electronic keying check is performed. Typically, three
keying option are available:
• Exact Match
• Compatible Keying
• Disable Keying
You must carefully consider the benefits and implications of each keying option
when selecting between them. For some specific module types, fewer options are
available.
Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
197
Appendix B
Using Electronic Keying
Electronic keying is based on a set of attributes unique to each product revision.
When a Logix5000 controller begins communicating with a module, this set of
keying attributes is considered.
Table 63 - Keying Attributes
Attribute
Description
Vendor
The manufacturer of the module, for example, Rockwell Automation/Allen-Bradley.
Product Type
The general type of the module, for example, communication adapter, AC drive, or digital
I/O.
Product Code
The specific type of module, generally represented by its catalog number, for example,
1756-IB16I.
Major Revision
A number that represents the functional capabilities and data exchange formats of the
module. Typically, although not always, a later, that is higher, Major Revision supports at
least all of the data formats supported by an earlier, that is lower, Major Revision of the
same catalog number and, possibly, additional ones.
Minor Revision
A number that indicates the module’s specific firmware revision. Minor Revisions
typically do not impact data compatibility but may indicate performance or behavior
improvement.
You can find revision information on the General tab of a module’s Properties
dialog box.
Figure 51 - General Tab
IMPORTANT
Exact Match
Changing electronic keying selections online may cause the I/O
communication connection to the module to be disrupted and may result in
a loss of data.
Exact Match keying requires all keying attributes, that is, Vendor, Product Type,
Product Code (catalog number), Major Revision, and Minor Revision, of the
physical module and the module created in the software to match precisely to
establish communication. If any attribute does not match precisely, I/O
communication is not permitted with the module or with modules connected
through it, as in the case of a communication module.
Use Exact Match keying when you need the system to verify that the module
revisions in use are exactly as specified in the project, such as for use in highlyregulated industries. Exact Match keying is also necessary to enable Automatic

Appendix B
Firmware Update for the module via the Firmware Supervisor feature from a
Logix5000 controller.
EXAMPLE
In the following scenario, Exact Match keying prevents I/O communication.
The module configuration is for a 1756-IB16D module with module revision
3.1. The physical module is a 1756-IB16D module with module revision 3.2. In
this case, communication is prevented because the Minor Revision of the
module does not match precisely.
Module Configuration
Vendor = Allen-Bradley
Product Type = Digital Input Module
Catalog Number = 1756-IB16D
Major Revision = 3
Minor Revision = 1
Communication is prevented.
Physical Module
Vendor = Allen-Bradley
Product Type = Digital Input Module
Catalog Number = 1756-IB16D
Major Revision = 3
Minor Revision = 2
IMPORTANT
Compatible Keying
Changing electronic keying selections online may cause the I/O
Communication connection to the module to be disrupted and may result
in a loss of data.
Compatible Keying indicates that the module determines whether to accept or
reject communication. Different module families, communication adapters, and
module types implement the compatibility check differently based on the family
capabilities and on prior knowledge of compatible products.
Compatible Keying is the default setting. Compatible Keying allows the physical
module to accept the key of the module configured in the software, provided that
the configured module is one the physical module is capable of emulating. The
exact level of emulation required is product and revision specific.
With Compatible Keying, you can replace a module of a certain Major Revision
with one of the same catalog number and the same or later, that is higher, Major
Revision. In some cases, the selection makes it possible to use a replacement that
is a different catalog number than the original. For example, you can replace a
Rockwell Automation Publication 1756-UM001N-EN-P - November 2012
199
Appendix B
Using Electronic Keying
1756-CNBR module with a 1756-CN2R module. The release notes for
individual modules indicate the specific compatibility details.
When a module is created, the module developers consider the module’s
development history to implement capabilities that emulate those of the previous
module. However, the developers cannot know future developments. Because of
this, when a system is configured, we recommend that you configure your module
using the earliest, that is, lowest, revision of the physical module that you believe
will be used in the system. By doing this, you can avoid the case of a physical
module rejecting the keying request because it is an earlier revision than the one
configured in the software.
EXAMPLE
In the following scenario, Compatible Keying prevents I/O
communication.
The module configuration is for a 1756-IB16D module with module revision
3.3. The physical module is a 1756-IB16D module with module revision 3.2. In
this case, communication is prevented because the minor revision of the
module is lower than expected and may not be compatible with 3.3.

In the following scenario, Compatible Keying allows I/O communication:
The module configuration is for a 1756-IB16D module with module revision
2.1. The physical module is a 1756-IB16D module with module revision 3.2. In
this case, communication is allowed because the major revision of the physical
module is higher than expected and the module determines that it is
compatible with the prior major revision.
Module Configuration
Vendor = Allen-Bradley
Product Type = Digital Input Module
Catalog Number = 1756-IB16D
Major Revision = 2
Minor Revision = 1
Communication is allowed.
Physical Module
Vendor = Allen-Bradley
Product Type = Digital Input Module
Catalog Number = 1756-IB16D
Major Revision = 3
Minor Revision = 2
IMPORTANT
Disabled Keying
Changing electronic keying selections online may cause the I/O
communication connection to the module to be disrupted and may result in
a loss of data.
Disabled Keying indicates the keying attributes are not considered when
attempting to communicate with a module. Other attributes, such as data size
and format, are considered and must be acceptable before I/O communication is
established. With Disabled Keying, I/O communication may occur with a
module other than the type specified in the I/O Configuration tree with
unpredictable results. We generally do not recommend using Disabled Keying.
ATTENTION: Be extremely cautious when using Disabled Keying; if used
incorrectly, this option can lead to personal injury or death, property
damage, or economic loss.

If you use Disabled Keying, you must take full responsibility for understanding
whether the module being used can fulfill the functional requirements of the
application.
EXAMPLE
In the following scenario, Disable Keying prevents I/O communication.
The module configuration is for a 1756-IA16 digital input module. The physical
module is a 1756-IF16 analog input module. In this case, communication is
prevented because the analog module rejects the data formats that
the digital module configuration requests.

module is a 1756-IB16 digital input module. In this case, communication is
allowed because the two digital modules share common data formats.
Module Configuration
Vendor = Allen-Bradley
Product Type = Digital Input Module
Catalog Number = 1756-IA16
Major Revision = 2
Minor Revision = 1
Communication is allowed.
Physical Module
Vendor = Allen-Bradley
Product Type = Digital Input Module
Catalog Number = 1756-IB16
Major Revision = 3
Minor Revision = 2
IMPORTANT
Changing electronic keying selections online may cause the I/O
communication connection to the module to be disrupted and may result in
a loss of data.
